User Manual
The envelope modifies the loudness contour of a sound. It
takes a sound input and shapes it into something you’d hear
from an acoustic musical instrument, like a piano or saxo-
phone. This envelope has two controls: “attack”, which is how
long it takes to ramp up to maximum volume, and “decay”,
which is how long it takes to fade to silence again. You can
use its third bitSnap
TM
to trigger the envelope from different
sources, like the keyboard.
The filter has the biggest effect on the sound’s character or
“timbre”. It affects the timbre by changing the relative volume
of certain frequencies in the sound. Use it to give the impres-
sion that a sound is “brighter” (more high frequencies) or
“darker” (more low frequencies.) The “cutoff” knob sets the
frequency to be emphasized, and the other controls “peak,”
or intensity of the filter. If the “peak” is turned up all the way,
the filter turns into an oscillator!

MODULATORS
Modulators are elements of a synthesizer that
alter the main audio signal with another signal.
In the synth Kit, they are the oscillator,
envelope and random modules.
Even though the oscillator is a signal
generator, it can also be used as a
modulator. You can turn the pitch knob fully
counterclockwise to produce frequencies low
enough to control other modules.
When the random module is in “random
voltages” mode, it is also a modulator.
